Also known as:

Comments: The deletion spans 70 to approximately 105 kb on the α-globin gene cluster (positions 169843-239896 according to the UCSC Genome Browser, March 2006) removing both of the duplicated α-globin genes and contiguous LUC7L and ITFG3 genes. The 5' breakpoint region lies between the HBA1P and HBA2 genes, while the 3' breakpoint is between the ITFG3 and RGS11 genes. This deletion was detected in a Bazilian child of mixed ethnic origin (European and African) with HbH disease.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
